MACHINE FOR STAGKING, WEIGHING, AND FEEDING BISCUITS.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed June 6, 1913. Serial No. 772,144.

T0 (at whom it may concern Be it known that I, GEORGE SAMUEL BAKER, a subject of the King of England, residing at London, in England, have invented certain new and useful Improvements in Machines for Stacking, WVeighing, and Feeding Biscuits, of which the following is a specification.

This invention relates to improvements in machines for stacking, weighing and feeding biscuits and the like.

In the machine constructed according to this invention, the biscuits are first placed haphazard in an oscillating tray from which they pass to endless belts provided with fingers or prongs, which, combined with a traveling brush, arrange the biscuits on end or in stacks and pass them to an electrically operated or controlled weighing device which automatically weighs or determines short weight of the biscuits which are then fed from the weighing device to be dealt with as desired. The whole machine is thrown out of action in case of an insuflicient supply of biscuits to the weighing device and requires to be manually started again.

In the accompanying drawings, Figure 1 is a side view of the stacking device, and Fig. 2 a plan viewthereof. Figs. 3, 4 and 5 are an end elevation, side elevation and plan respectively, of the weighing device. Fig. 6 is a detail view showing an electrically controlled mechanism for controlling the balance of the weighing device, and Figs. 7 to 10 detail views of a slide and coacting parts by which the biscuits are delivered from the weighing device, Fig. 7 being a plan view, Fig. 8 a detail view of parts shown in Fig. 7,

Fig. 9 a section on the line 99 of Fig. 7,

and Fig. 10 a section on the line 1010 of Fig. 7.

Referring to Figs. 1 and 2, the stacking attachment comprises a standard 130 carrying at one end an inclined feed tray 131 mounted on pivoted levers 132 adapted to be rocked by any suitable mechanism operated by drive 132 to impart a shogging motion to said tray. The tray 131is adapted to discharge the biscuits placed haphazard thereon into a chute 133 which carries them onto a conveyer belt 134 provided with perpendicular plates 135, and traveling around pulleys 136, 136 mounted in arms136 extending from the standard 130 and driven by pulley and belt gear 137, 138. The said belt 134 passes between two other conveyer belts 139, 139 passing over pulleys 136, 140, 140 and 141, and the plates 135 on said belt 134 impart to the biscuits a vertical position on the lateral belts 139 which position is maintained by the endless brush 142 traveling at the same speed and in the same direction as the belts 139. The brush 142 is driven from the belts by means of pulleys 143, 144 and chain 145.

From the stacking attachment described the biscuits are passed to the weighing attachment which is asfollows, reference being made to Figs. 3 to 6. The biscuits on the belts 139 (Fig. 5) are fed by the transversely movable feed plate 146 onto the balance147. The said plate is operated by the lever 148 and connecting rod 149, lever 150, rocking shaft 151, catch lever 152 and a cam-piece or surface 152 on the continuously rotating half toothed wheel 153 driven from the shaft 153 by chain and pulley gear 154, 155. The said wheel 153 is in gear with a wheel 156 in the ratio of three to one, said wheel 156 operating the feed slide or box 157 (hereinafter fully described with reference to Figs. 7 to 10 to feed the biscuits from the balance 147) by means of connecting rod 158 and crank 159 in such a manner that biscuits are fed intermittently.

The actual weighing device is electrically operated and represented in Fig. 6 and is so constructed that if insuflicient biscuits, according to a predetermined weight, are fed to the balance 147 a clutch is caused to be thrown out of gear and the machine stopped. A time cam 163 is provided on the shaft 153 having a cam surface 163*. So long as the weight of the biscuits on the balance is correct a contact 165 on the stem of the balance engages a contact 166 in a circuit containing a solenoid 167 and the cam 163 in its rotation will act upon a contact maker 168 to engage a contact 169. so that the circuit 170, 171 containing battery 172 is closed and an armature 173 on the end of a rod 174 is attratced V by the solenoid and said rod acts on a bell crank 175 normally lying between a lever 177 (connected to c1utch'17 9 by means of a rod 178) and a cam 17 6'to remove said bell crank so that the cam has no effect on the lever and the clutch 179 remains in gearas shown in Fig. 3. Should, however, the weight be insuificient the arena remiss 157 see also Fi l works in a guide open, the rod 174; is not attracted and the bell crank 175 remains between the cam 176 and lever 17 7 in which position the cam entering between the bell crank and lever moves the lever on its fulcrum to disengage the clutch and thus stop the machine. The clutch is normally held in engagement by a spring 17S on rod 17 8 and may, when necessary, be thrown out of gear by means of a pedal 178 shown in Fig. 3.

The weighing device is actuated from the pulley 200 on a shaft 201 carrying loosely a gear 203 having integral therewith one portion of a clutch 179, the companion portion of which is splined to a shaft 201. The gear 203 meshes with a gear 204: on a shaft 153 After the weighing the biscuits are fed forward by the slide or box 157 before referred to, for example onto a holder 35 mounted on a reciprocating carriage 70 in a wrapping machine which is fully described in the specification of my application dated concurrently herewith, Serial No. 728,206. Reference is directed to Figs. 7 to 10. Between the weighing balance 14:7 and the holder there is provided a pair of guides 220 in which slides a plate 221.

adapted to support the biscuits. The slide 222 and comprises the side member 223, backend plate 223* having a cut away portion 223", and front-end plate or clip 223 pivoted to the member 223. This latter also carries an arm 223, the purpose of which is hereinafter explained, and the back-end plate carries a spring catch or trip 223 which is adapted to engage a loop 221 of the plate 221 to move the plate between the balance 1 17 and holder 35 during the reciprocating movements of the slide 157 and to release said plate 221 when the latter reaches the end of its travel in either direction. On the pivot of the front-end plate 223 is a trip hook 223 adapted when the slide is in the position illustrated in Fig. 7 to be engaged by a spring catch 225.

63 designate biscuit clips of the holder 35 as described in the aforesaid application,

these clips 63 being adapted to grip the ends of the biscuits, the resilient action of said carried b T carria e 70 a sleeve 226 carrvin D s D a spring drum 226 tending to keep the right j hand clip 63 in the position shown in full lines in Fig. 7, that is to say, lying substantially within the cut out portion 223 of the back-end plate 223 as shown in Fig. 10. The drum 226 is also in operative connection with a hook 226 and the frame of the machine carries a spring finger 227 hav-' ing thereon a pin 227 adapted to engage said hook and also to be engaged by an arm 228 attached to the back-end plate 223. This sleeve 226 and bevel wheel 67 are adapted to be rotated together by means of intercoacting abutments 228 and 228 on the sleeve and pinion respectively but the sleeve is capable of rotation independently of the pinion for the purpose of permitting the clip to be moved into the position shown in broken lines in Fig. 7, or in full lines in Fi 8.

The action of the parts above described is as follows :The slide 157 is normally over the weighing balance M7 and receives the weighed stack of biscuits between the end plates 223 and 223 After the weighing is completed the slide moves toward the left'in Fig. 7 taking with it the plate 221 by engagement of the spring catch 223 with the loop 221 until said plate abuts against the edge of the holder 35, whereupon the catch leaves the loop and the slide continues its movement to the left until it arrives in the position shown in said Fig. 7, by which time the biscuits have been deposited on the holder. To enable this to be effected it is necessary that the right hand clip 63 should be in the position. shown in dotted lines. This is brought about during the return stroke of the carriage by the spring finger 227 on the machine frame engaging the hook 226 on the carriage so that at the end of the return stroke the parts will be in the position shown in Fig. 8, in which position the hook 226 is in engagement with the spring finger 227 thus holding the clip open, but when the slide arrives in the position indicated in Fig. 7, the arm 228 en gages the pin 227 of the spring linger 227 and forces the latter out of engagement with the hook 226 allowing the right hand clip under the action of the spring drum 226 to assume the position shown in full lines. 227 is an abutment for limiting the movement of the finger 227 in the right hand direction. The arm 223' carried by the side member 223 now engages a spring 229 having thereon a pin 230 which normally holds the rack 69 (referred to in the aforesaid application) in position in which the clips 63 are as indicated in full lines in Fig. '7. By such engagement of the arm 223 and spring 229 the rack is released and the spring 6-1- acts through the bevel wheels 66, 67 abutments 228 and 226 to bring the clips 63 into fully closed positions, thus gripping the biscuits. Simultaneously with the movements described the trip hook 223 has been engaged by the spring catch 225 so that on return movement of the slide toward the right the front-end plate 223 is moved into the position shown in dotted lines so as to allow the slide to return and leave the biscuits on the holder.
